   - 未迁：`try_sync_editor_overlay_state`、`on_selection_change` overlay 同步、`drop_indicator_from_target`、拖拽 listener 和 block reorder 行为。
+- 2026-05-25：Batch S 只派发 1 个只读 Reasonix worker 审计 `try_sync_editor_overlay_state` 迁出边界，使用独立 worktree `/mnt/Data1T/mnote-worktrees/0525-s-worker-a-5-29-overlay-sync-readonly`，run id `reasonix-2026-05-24T20-44-23-926Z-3436b5dd`，并显式使用 `--no-memory-recall`。
+  - Codex 已读取 Hindsight recall、`process-handoff.md/json`、`result.json`、`final.md`，并核对 worktree `git status --short` / `git diff --stat` 为空；Reasonix 未修改源码。
+  - 审计结论经 Codex 复核后采纳：`try_sync_editor_overlay_state` 已无 `lib.rs` 私有依赖，只依赖 `editor_focus::active_editor_stage`、`floating_toolbar_anchor_from_selection`、`try_close_block_menu_overlays`、`FloatingToolbarAnchor` 和 `HoveredBlockState`，可机械迁入 `editor_runtime/overlays.rs`。
+  - Codex 主控完成迁移：`try_sync_editor_overlay_state` 迁入 `editor_runtime/overlays.rs`，`lib.rs` 仅保留 mouseup / keyup listener 调用和仍属于 shell 的 DOM / selection bridge 编排；清理本次迁移产生的孤儿 import。
+  - 修改：`rust/spikes/leptos-tiptap-spike/src/editor_runtime/overlays.rs`、`rust/spikes/leptos-tiptap-spike/src/lib.rs`、generated island `js/wasm`。

+  - 未迁：`on_selection_change` overlay 同步、`drop_indicator_from_target`、拖拽 listener、block reorder 行为和 selection bridge 仍留在 `lib.rs`。
